Default Expected power gain on Cobb stage 2 car with Borla header install?

Just received mine today from NOPI. They shipped it out a day after I placed an order. My concern is whether Cobb stage map can benefit from Borla header.

Weld quality and fitment seems very good although I haven't installed it yet.

Perhaps you should e-mail Cobb and ask them (as it says on their AP website).

By the way... you think the fitment is good when you haven't even had a dry-run yet??
You've got a hell of an eye, then

I'm actually interested in what you find because I'm installing my Borla headers this weekend.

Take a look at my dyno thread (too lazy to find it right now). I really didn't get much of a gain from headers, but I'm pretty sure they are keeping the EGTs nice and low.

Heres your answer: I am also running the cobb stage 2 map with all the goodies, uppipe, dp, 3" TBE, and I installed my headers and I had the same question.."is this gonna be safe?" Well yes it can be only if you do it the right way: Once you install your headers you MUST reset your ECU by disconnecting the negative terminal on the battery and by pumping the brakes to drain any power left in the system(this just makes it reset quicker), the reasoning behind this is because your ecu once it flashed with the stage 2 map is not in a learning mode anymore it knows the map, and thats all it knows, to make your ECU "learn" the mod you must disconnect the negative terminal on the battery, let it reset, then this is the single most important thing( when you start the car dont touch anything! just let it run, dont hit the gas at all dont move just let it run for about 3 minutes, then shut it off. You must shut it off once before you go for a spin that way your ECU has learned the new airflow/velocity for timing, fuel delivery, etc. Now restart and drive you will feel the difference with the headers and now its safer than the ECU not recognizing it at all. And no resetting your ECU will not require a reflash, unless your using a Realtime cobb map, but if its the regular Basemap then it is already stuck in your ECU's database so resetting the computer will NOT erease the flash. Hope this helps..

Why do you want your EGTs nice and low? The main thing that drives the turbine is delta T.

Anyways, a 4 to 1 is better than the stock bendy straw even if you only gain 1HP.
